AWNING WINDOW LOCKING MECHANISM Filed Feb. 11, 1959 2 Sheets-Sheet 2 I2 INVENTOR. AL BRENNER ATTORNEY United States Patent Ofiice 2,898,645 Patented Aug. 11, 1959 2,898,645 AWNING WINDOW LOCKINGMECHANISM V Al Brenner, Miami Beach, Fla.

Application February 11, 1959, Serial No. 792,641 5 Claims. (Cl. 20- -42) This invention relates to awning windows and is more particularly directed to operating mechanism for automatically locking the vents of an awning window when in a closed position.

By virtue of the unique construction of awning windows, there is some play or looseness in the joint movement of the vents and the actuation mechanism. This condition that is more or less inherent in the present awning windows is especially critical when the vents are in their closed position where it is possible to force open the vents a slight distance without the necessity of actuating the operating handle. Obviously, a window that does not seal tightly and remain thusly as long as the operating handle is not actuated is not desirable nor eflicient, since there will be a leakage of air therethrough, and also the danger of a burglar being able to force the opening of the vent from the outside of the window.

dow comprising a header 11 and sill 12 with a vertical stile or jamb 13 joining the ends of the header 11 and sill 12 to form a rectangularly shaped frame for a plurality of vents 14 mounted for vertical swinging movement thereon. The vents 14 are provided with a rec tangular frame 15 having a Z-shaped cross section to which the vents are secured as by a mound of glazier putty 17 positioned against the edge of the glass vent 14 and a side wall 18 of the vent frame 15.

Along the upper end portion of each of the side walls 18 of the vent frames 15 there is secured a vent hinge 19 as by screws 20 countersunk thereon to permit the free pivotal movement of vent links 21 whose upper end is pivoted by a pivot pin 22 to the lower end portions of each of the vent hinges 19. The upper ends of the vent hinges 19 are slightly arcuate as shown extending beyond the top of the vent frame 15 to the inner portion of the jambs or stiles 13 where they are pivotally secured as by pivot pin 23 to slide bar 24. The lower ends of the vent links 21 extend downwardly to the window frame where the ends thereof extend through slots (not shown) in the frame and are pivotally secured by pivot pins 25 mounted within caps 26 adjustably secured to the frame.

The slide bar 24 is slidably mounted along each of the jambs or stiles 13 by means of a plurality of brackets 27 secured to the stiles 13 by a screw 28. At the lower end portion of each of the slide bars 24 there is a pivot pin 128 pivotally mounting one end of a link 29 whose other end is pivoted as at 3t) to the outer end of cross shaft arm 31. The inner end or" each of the cross shaft arms 31 is secured to a cross shaft 32 that extends along the A principal object of the present invention is to provide an awning window with an operating mechanism that locks the vents as the latter arrive at their closed position and automatically release the vents as the operating mechanism is actuated to open the vents.

Another object of the present invention is to provide an awning window with an operating mechanism which trips a simple locking device for locking the vents in their closed position.

A further object of the present invention is to provide an awning window with an automatically locking device which prevents there being any play or movement of the vents when in the closed position unless the operator handle has been first actuate With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with. the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a perspective view of an awning window in which my automatically operated window locking device is embodied.

Figure 2 is a longitudinal sectional view taken along the line 2--2 of Figure 1 showing the vents in the open position.

Figure 3 is a similar view with the vents swung to the closed position and the locking devices" actuated to secure the vents.

Figure 4 is a detailed sectional view taken along the line 4-4 of Figure 3.

Figure 5 is a cross sectional View taken along the line 5-5 of Figure 4. 7

Referring to the drawings wherein like numerals are used to designate similar parts throughout the several views, the numeral 10 refers generally to an awning wintional movement of the sector inside wall of the sill 21 for its full length with the ends of the cross shaft 32 journalled in suitable sockets (not shown) mounted on or secured to the jambs 13.

On one of the jambs 13, at the lower inner surface thereof, an operator housing 33 is mounted. Within the operator housing 33, there is a sector gear 34 pivotally mounted as at 35. The sector gear is provided with an arm 36 which has a slide pin 37 mounted at the free end thereof. The slide pin 37 is slidably mounted in a slot 38 formed in the cross shaft arm so as to transform rotagear 34 to translatory movement of slide bar 24 as is explained in greater detail hereinafter. An operator handle 40 mounted on the housing 33 for rotational movement is provided with a worm gear 41 which is in mesh engagement with sector gear teeth 42. of the sector gear 34. V

Means are provided for locking the vents 14 in a closed position comprising a lever type latch 43 pivoted adjacent its lower portion 143 by the pivot pin 23. The latch 43 is positioned between the vent hinge 19 and the slide bar 24 and is made to travel in a vertical direction with the slide bar 24. There is a latch 43 mounted on each of the pivot pins 23 (except the topmost pivot pin 23) on each of the top end portion of the slide bars 24. On the inside wall of the jambs 13 there is a plurality of pins 44 mounted alongside" the slide bar 43 adjacent the inner edge only of the slide bar 24. The pins 44 are so that as the slide bars ing of the vents 14, 43 Will engage the 3-5, inclusive.

positioned on the jambs 13 the lower portion 143 ofthe lever pins 44 as best shown byFigures' 24 slide upwardly during the clos Also in cooperative engagement with the outward end 243 of the latch leverl43 is a: pin 45 mounted.v

with the outer end 243 engaging the pin 45 to lock the vent 14 in its closed position.

When it is desired to open the vents 14 of the awning window 10,- the operator handle 40 isrotated .to cause thesector. gear 34 and arm 36 to pivot about the pivot pin 35 andswing in a downwarddirection. The slide pin 37 is made to slide downwardly in'the slot 38 and the cross shaft arm'31 to swing about the cross shaft 32, which in turn rotates. Both cross shaft arms 31 now swing to draw the links 29 and slide bars 24 slide downwardly, the locking lever 43 is made to pivot on its pivot pin 23 to an approximately horizontal position, moving from the solid line position to the dotted line position as shown by Figure simultaneously with the outward swinging of the vent 14 from its closed position to its partially open position as shown by the dotted'lines; The outward swinging movement of the vent 14 causes the latch pin 45 to bear against the end portion 243 of the latch lever 43 and swing it downwardly as the latch lever 43 moves downwardly with the slide bar 24 away from the locking pin 44 which heretofore prevented the swinging movement of the latch lever 43. The window vents 14 now are in their-open position.

7 To close and lock the vents 14, the operator handle 40 is turned in a reverse direction and the slide bars 24 now slide upwardly carrying the pivot pins 23 in an other on said window frame for vertical swinging movement from said window frame, pivot means mounting the upper end of each of said vents to said slide bar, a vent link pivotally mounted at one end to each of said vents and the lower end to said window frame, latch means mounted on said slide bar, latch engaging means mounted on said vents, abutting means mounted adjacent said slide bars whereby upon the simultaneous sliding" of said slide bars and closing said vents, said abutting means engagessaid latch means and effects the locking of said vents by the engagement of said latch means with said latch'engaging means;

3. An awning window comprising a window frame having a pair of vertically disposed jamb portions, a slide bar slidably mounted along each of said jamb portions, a plurality of vents positioned one above the other on said window frame for vertical swinging movement from said window frame, pivot means mounting the upper end upward direction and thereby causing the vents 14 to swing downwardly toward their closed position. When the vent 14 has reached the dottedjline position, the latch lever 43 will have arrived in juxtaposition with the lockingpin 44 as shown by dotted lines and the latch pin-45 will be positioned as shown by dotted lines. The locking pin 44 will impinge against the end 143 of the latch lever 43 to cause the latch lever. to pivot about the pivot pin 23'With the end portion 243 swinging upwardly until it engages the latch pin 45 all of which have now moved to their solid line positions. The vents 14 are now locked in their position so that the vents'14' cannot be pried open from the outside. With the latch lever 43 engaged at its ends 143 and 243 by the pins 44 and 45 respectively, the vents 14 will be'locked tightly against the window frame of the awning window 10 so that at no time'is there not the usual play or slack between the vents 14 and the window frame of an awning window.
